Tony Doyle - University of Glasgow GridPP Mid-Term Review 1.What has been achieved in the first 18 months? Oversight Committee (May 2003): Conclusion "Excellent progress, management, control, reporting and thinking (both tactical and strategic), we look forward to an equally successful second half of the project as the investments made translate into middleware roll-out and benefits to the HEP experiments. It is difficult to imagine more impressive progress all round." 2.Development in the medium-long term?

Tony Doyle - University of Glasgow What impressed the Oversight Committee? (I) Identifiable progress via tasks and metrics “At the midpoint of the project, over half of the 182 tasks are completed and all of the 44 metrics are within specifications. The Project Map incorporates a complete Risk Register with 76 identified risks, reviewed on a regular basis.”

Tony Doyle - University of Glasgow Why were the Oversight Committee convinced? (III) Identifiable progress via testbed monitoring “All testbed sites can be said to be truly on a Grid by virtue of their registration in a comprehensive resource information publication scheme, their accessibility via a set of globally enabled resource brokers, and the use of one of the first scalable mechanisms to support distributed virtual communities (VOMS).” UK-wide development using EU-DataGrid tools (v1.47). Not yet robust, but sufficient for prototype development. See What were the Oversight Committee looking forward to? (I)

Tony Doyle - University of Glasgow Where will we be in September 2004? Applications will be using the Grid for their Monte Carlo production. Typically low level usage (~5% of the CPU and ~1% of the storage). EDG will have completed its task of providing prototype middleware. EGEE will be in progress with more emphasis on a common infrastructure for a broader range of applications. Testing of LCG Phase 1 will be well underway. A prototype Tier-0 Centre will be linked to the Regional Tier centres based on the LCG releases. GridPP1 will be completing its task of developing and deploying a prototype Grid in the UK. A prototype Tier-1 Centre will exist based at RAL. Tier-2 centres will be being built up from hardware provided by the Institutes. The UK testbed will be fully integrated with the LCG testbed. The prototype Grid will have been rolled out to Institutes across the UK. Experiment applications will have been developed to various levels of functionality. Grid computing will be expected to provide for the requirements of all experiments.

Tony Doyle - University of Glasgow What will we need to do in September 2004? Full functionality production Tier-1 Centre needs to be developed. Tier-2 centres will need to be developed and integrated. The software development (verification, validation and testing) cycle will need to conform to industrial standards. EGEE will have assessed middleware. Dependent upon LCG for its operations centre. In the UK, the Grid Support Centre will have expanded its role. Need to incorporate anticipated wider participation, a move from Monte Carlo production to a full Physics Analysis environment The applications must be fully developed, tested and exercised in a production Grid environment. Scale? The total CPU capacity corresponds to ~7000 kSI2000 (or 20,000 PIII 1GHz processors) and 750 TBytes of disk storage in Sept LCG will need to build the full facility needed by the LHC experiments including Tier-0 and Tier-1 resources at CERN. We will need to ensure that our deployment plans are fully interoperable especially where resources are shared with other disciplines.
